SCHAAF ExpaHubConnection scheme for economical wheel hub and shaft

SCHAAFofExpaHubCan be applied to any application where a hub with a cylindrical inner hole needs to be installed on the shaft. By using hydraulic tools, tighten the flange/The conical sleeve between the hub and the shaft is connected together to obtain the required radial expansion force.

feature

Because there is no need to forge the flange during shaft manufacturing, it can save materials and processing costs.

Capable of transmitting large torque without any gaps

Separable and removable hydraulic nuts——Can be used for connecting multiple clutches

Ensure the torsional and bending strength of the connection when there is a change in speed, torque, or direction of rotation

After years of use,ExpaHubCan still be easily and quickly disassembled

Can be reused after disassembly——cost saving

The standard hydraulic expansion bolt consists of the following components:

TThe conical bolt and sleeve are made of high-strength quenched and tempered steel, which can withstand large shear and axial loads.

Two high-strength round nuts

Fine thread, high fatigue strength

The pressure connection port and oil groove facilitate easy disassembly of bolts .

Application field

SCHAAFofExpaHubHydraulic couplings can be used in any situation where flanges or hubs with cylindrical inner holes need to be installed on the shaft. Hydraulic tools can be used to press the taper sleeve between the flange or hub and the shaft, thus generating radial clamping force.
